Lopez allowed four runs on seven hits with one strikeout and a walk over 3.2 innings during a no-decision against the Nationals on Friday.
The 23-year-old continued his pattern of alternating fantastic outings with terrible ones. In two of his last four starts, Lopez has pitched at least six shutout innings. During the other two, he's yielded a total of 14 runs in 6.2 innings. It hasn't averaged out in his favor, as his ERA has jumped nearly a run and a half during this four-game span. Lopez is now 3-5 with a 5.40 ERA, 1.24 WHIP and 50 strikeouts in 51.2 innings. He is scheduled to pitch next against the Giants on Wednesday.
